Just hung up Ge Xiong's phone, and the mobile phone rang again, Duan Zifeng saw that it was an unfamiliar phone number, and the area code was Beijing.

"Xiao Feng, you haven't forgotten me, old fellow, have you?"

"Grandpa Ouyang!" Duan Zifeng exclaimed in surprise and said, "How could I forget your old man?

"Hehe!" The old man recognized his voice when he heard Duan Zifeng, laughed heartily, and said: "When you are old, what you are most afraid of is to say goodbye! So I don't even know Xue'er, Xiaofeng! Have you been free lately? If you are free, can you come to the capital?"

Duan Zifeng asked a little strangely, "Is there something wrong?"

"You boy, am I looking for you only because I want you to be cured?" said the old man, feigning anger, but immediately laughed again, "Alas! But you really guessed it, but it's not me, but an old friend of mine, his physical condition has been getting worse and worse recently, and now he is hospitalized, I originally wanted to take him to Quhe to find you, but his health care doctor and family disagreed, so I wondered if you could come to the capital and show him if there was any possibility of recovery, because the current diagnosis is not optimistic, they estimate that he can only lie on the hospital bed in the future, and he will be able to survive for more than a year!"

"Are you in a hurry? Because there are still some things to do the day after tomorrow, if you are not in a hurry, I will take leave on Monday!" Duan Zifeng asked.

Hearing that Duan Zifeng agreed without the slightest hesitation, the old man Ouyang was very relieved, and said: "Don't worry, although you are seriously ill, if the assessment of those experts is not wrong, there will still be more than a year in time! In this way, I will ask your uncle to prepare a ticket for you, and the day after tomorrow you will fly directly over, and I will let someone come to the airport to pick you up! I just need you to take two days off, it will not affect your study, right?"

"It's okay, in fact, all I learn now are some basic theories, and it's almost the same to read the book by myself, but the ticket is forgotten, and I may not be free the day after tomorrow, so I'll buy it myself when it's confirmed!" Duan Zifeng said.

"That's fine, but you have to call me in advance before you come over, so I can have someone pick it up, by the way, how is Xue'er doing during this time?

"Haha!" Duan Zifeng smiled: "Of course our relationship is quite good, she invited me to dinner yesterday!"

Remembering that yesterday Ouyang Xue completed the gambling contract in order to make a simple request casually, and invited herself to dinner with a flattering look, although the final result was that Ouyang Xue was annoyed and ashamed, Duan Zifeng was very happy, and felt more and more that it was a very enjoyable thing to occasionally tease this elf-like girl.

"Really?" the old man said in surprise: "I'll just say it! You two are very right! Xue'er has a tender face, as a boy, you have to take the initiative to know? I'll tell you......"

Listening to the old man Ouyang babbling about some of Ouyang Xue's past events and her preferences and interests, the whole thing was a posture of giving advice to Duan Zifeng, and Duan Zifeng became embarrassed from being happy.

Finally finished perfunctory, Duan Zifeng found that he was already in a cold sweat, this Ouyang Grandpa, he really spared no effort to match himself with his granddaughter!

After answering these two phone calls, Duan Zifeng also dispelled the idea of continuing to go to the library, considering that he also learned some practical acupuncture techniques, but he didn't have the right tools, so Duan Zifeng walked out of the school gate and took a taxi to the pharmacy.

Most pharmacies do not sell acupuncture tools, and after looking for many ones, I got a positive answer in a relatively large pharmacy, but when the boss took out a set of acupuncture needles from the counter, Duan Zifeng found that there were no needles as described in the blood separation acupuncture.

The boss listened to Duan Zifeng's description and said with a smile: "We only have commonly used conventional needles here, the single-sided bladed needles you are talking about, I have never heard of them, with all due respect, are you looking for that kind of needle, is it really used for acupuncture?"

"Of course, it's for acupuncture, and it's described in detail in an ancient medical book I got!" Duan Zifeng replied.

The boss also seemed to know something about acupuncture, and said: "As far as I know, there are nine kinds of acupuncture needles in ancient times, and most of them have been abandoned.

From the boss's expression, Duan Zifeng seemed to be doubting the authenticity of the medical book he obtained, and couldn't help but smile bitterly, but people are also kind-hearted, for a stranger who meets for the first time to have such a advice, it can be regarded as kind-hearted, as long as the average businessman can sell his own things, it doesn't matter if you go to kill or set fire!

"Boss, don't worry, I'm a student at the Medical University, if I'm not sure, of course I won't use it casually!" Duan Zifeng said sincerely.

"Oh! No wonder! I am too worried about this, but the kind of needle you are talking about is really not, not only I here, but also in other places, unless it is to find a manufacturer to customize, but this is probably difficult, people a factory, small batch orders are not accepted at all, even if you are willing to help, the price is also very expensive. The boss patiently explained.

Duan Zifeng was silent, finding a factory to customize is indeed a method, but it takes time and a way, not something that can be done in a short time, while nodding and casually looking at the several needles taken out by the boss, suddenly his eyes lit up, and a flat needle appeared in Duan Zifeng's eyes.

The boss saw Duan Zifeng pick up this needle and explained: "This is called a bladed needle, but it is not a side blade, but a top blade, which is far from the needle you said." ”

Duan Zifeng smiled: "Boss, I'm going to have this kind of blade needle, how many do you have here?"

"This kind of needle also belongs to a special category, and there are not many of them, about more than 200 of them. The boss replied in surprise.

"That's not that much, so let's just give me twenty, how much?" Duan Zifeng said with a smile.

"Originally, it was three dollars a piece, so it's cheaper for you, two dollars!, but does this needle really work?" the boss asked suspiciously.

Duan Zifeng said while taking out the money: "Of course it's useful, I won't spend money to buy some useless things! Thank you, boss, this is forty yuan." ”

Duan Zifeng didn't say that he wanted to directly use the blade needle instead of the knife needle, but the two were very close in shape, he wanted to do it himself and process it a little, and sharpen the blade needle into the shape of the knife needle, anyway, it won't be used on people now, as long as it's about the same, it can be tested and used on the model.

After thanking the boss, Duan Zifeng kept going, bought a whetstone in the supermarket, and returned directly to the Medical University, first in charge of a craft, Duan Zifeng was enthusiastic, in Tian Yu's curious eyes, Duan Zifeng took a glass of water with a water cup, came to his room, and closed the door, took out the needle and whetstone, to process this needle less than a millimeter thick, of course, it is necessary to be extremely careful.

Sure enough, even though Duan Zifeng's eyesight and control are beyond ordinary people, and he is careful and careful, but the first time he tried this kind of work, the needles were too small, and he destroyed a few without paying attention.

Duan Zifeng was not discouraged, and was more dedicated to grinding, first using coarse sand grinding surface to roughly polish the shape, and then using fine sand grinding surface to slowly grind out the sharp blade, and after destroying a few, Duan Zifeng finally mastered the trick, and the needle in his hand began to taste a little like a knife needle!

At this time, Duan Zifeng's eyesight played a role, under the full attention, the blade surface gradually formed, gradually sharpened, you know, the overall width of the needle is only about one millimeter, such a small stainless steel needle to grind out the blade, all by manual operation, the difficulty is not a star and a half, because the processing of the blade surface is not only sharp, the most important thing is not to deviate, the entire blade surface is above a level, and it needs to be smooth, there can be no uneven thickness or gap.

After more than an hour of busy work, the first knife needle was finally completed in Duan Zifeng's hand, looking at the knife needle that he had worked hard to transform in front of him, Duan Zifeng was overjoyed, with this needle, when he learned the blood separation needle, he was no longer completely on paper, just like a soldier, after training for a long time, he finally got the weapon in his hand, although he couldn't kill the enemy right away, but the training with weapons and the training without weapons felt completely different!

Seeing that Duan Zifeng finally came out of the room, Tian Yu, who was watching TV, asked curiously: "Xiaofeng, what are you doing in the room mysteriously? Are you studying your acupuncture again? It's not that I said you, it's good to learn things, but you have to have a degree, what have you become during this time? I took your broken book with me in the bathroom! Isn't that book magical? Sister burned it!"

Duan Zifeng walked over and sat next to Tian Yu, and said with an excited smile: "Sister Yu! Look! This is the knife and needle I sharpened myself!

Seeing Duan Zifeng hand over a needle as if offering a treasure, Tian Yu looked at it again and again suspiciously, and then touched Duan Zifeng's forehead with his hand, and said strangely: "You don't have a fever! Aren't you just an ordinary acupuncture needle?

"Of course it's different!" Seeing that the work he worked hard to make was despised, Duan Zifeng said aggrievedly: "This is made by me!

Tian Yu looked at it carefully, only to find that it was really a little different, and curiously touched the blade surface with his finger, Duan Zifeng didn't have time to stop it, and saw Tian Yu quickly retract his finger as if he was electrocuted.

Duan Zifeng hurriedly pulled Tian Yu's hand and looked at the hand that was cut by the knife and needle, fortunately, the needle was small and forceless, but it only slightly cut a layer of epidermis, and there was only a red mark on the finger, and there was no blood.

"Oh, it's so sharp! It's comparable to a scalpel!" Tian Yu said in surprise.

But seeing Duan Zifeng nervously pulling his palm to check carefully, Tian Yu couldn't help but feel a little strange, I don't know why, when facing Duan Zifeng, Tian Yu didn't have any resistance at all, and this phenomenon is getting more and more serious, it used to stop at hugging, but now it seems that even holding hands needs to be taboo!

"Fortunately, it wasn't cut, this hasn't been poisoned, Sister Yu, you're too careless!" Duan Zifeng blamed.

Tian Yu hurriedly pulled his palm back, and said with a pretense of disgust: "Who told you not to say it earlier? Anyway, what are you doing with such a needle? Do you want to start practicing?"

Duan Zifeng smiled: "Yes, does Sister Yu want to be my first experimental subject?"
